24.09.2015 - Parliament adopted the amendment of the Stock Exchange Act on 28 September 2012. The legislative revision entered into force on 1 May 2013. The changes will bring the Stock Exchange Act into line with international requirements. In particular, the insider criminal law provisions will be overhauled and the constituent elements of price manipulation stated more precisely. Insider trading and price manipulation will now be prohibited for all market participants. Both offences will be treated as crimes. The revision will improve the protection of individual market participants and enhance the reputation of Switzerland's financial centre.
